If you are going to use a brake light for the activation circuit of a brake controller like the Prodigy P3 part # 90195 the brake circuit needs to be one that does not activate with the blinkers. A third brake light is typically the ideal circuit for this.
Another easy solution is to use a universal stoplight switch kit part # RM-751000 which will give you the dedicated stoplight circuit needed.
You should also try increasing the brake controllers gain setting to see if that allows the controller to activate the trailer brakes.
